Global biodiversity loss and its consequences for human welfare and sustainable development have become major concerns. Economists have, therefore, given increasing attention to the policy issues involved in the management of genetic resources. To do so, they often apply empirical methods developed in behavioral and experimental economics to estimate economic values placed on genetic resources. This trend away from almost exclusive dependence on axiomatic methods is welcomed. However, major valuation methods used in behavioral economics raise new scientific challenges. Possibly the most important of these include deficiencies in the knowledge of the public (and researchers) about genetic resources, implications for the formation of values of supplying information to focal individuals, and limits to rationality. These issues are explored for stated-preference techniques of valuation (e.g., contingent valuation) as well as revealed preference techniques, especially the travel cost method. They are illustrated by Australian and Asian examples. Taking into account behavioral and psychological models and empirical evidence, particular attention is given to how elicitation of preferences, and supply of information to individuals, influences their preferences about biodiversity. Policy consequences are outlined.

From the mid-1970s through the 1980s and into the 1990s, wage inequality and skill differentials in earnings and employment increased sharply in OECD countries. After 1973 and especially in the 1980s, the US experienced a dismal real wage performance for the less skilled. Among the factors singled out by economists as possible major contributors to this development are economic globalisation processes and skill-biased technological change. Although these are most commonly considered as independent influences, after critically outlining views about these factors, this article argues that strong interdependence exists between them. The article then examines potential policy responses to this growing inequality.

This paper presents evidence from two survey's to help explain the poor ratings consistently given to the teaching of economics at Australian universities. The evidence suggests that the Poor ratings of economics teaching can be attributed to two related factors: inappropriate pedagogical practices and lack of rewards for allocating additional time to teaching. The survey data oil pedagogy, in economics consist of 205 responses from graduates from two Queensland universities. The time elapsed since graduation ranges from 1 to 10 years. The survey data on academics' time allocation consist of 290 responses from academic economists across a wide range of Australian universities.

O artigo trata do debate ocorrido entre Sismondi e os economistas ricardianos, na primeira metade do século dezenove, a respeito do equilíbrio dos mercados, do papel da competição e dos efeitos da maquinaria nas sociedades industriais. A seção inicial reconstitui os principais termos do discurso crítico de Sismondi direcionado à ortodoxia clássica. A seguir, detalham-se as respostas elaboradas por McCulloch e Torrens em defesa da livre concorrência, do caráter ilimitado da demanda e do avanço da mecanização na atividade produtiva. A terceira seção considera a argumentação posterior de Sismondi na qual ele reitera sua teoria das crises de superprodução a partir de uma abordagem histórica do capitalismo. Ao final, procede-se a uma breve avaliação da herança ricardiana à economia política em vista da controvérsia examinada.

The Portuguese arrival in India marked the beginning of the age of modern globalization that has been sustained until very recently in conditions that were favourable for the western domination of the globe. Adam Smith analyzed the origin of the wealth of nations in pre-Gamic and post-Gamic eras. It is presently experiencing tremors that were predicted by Andre Gunder Frank in his ReOrient, which the bulk of the western sociologists and economists sought to ignore. For Gunder Frank the past five centuries saw an ephemeral rise of the West, exploring and exploiting the pre-existent markets of China and India. He saw these making a comeback.

Most financial and economic time-series display a strong volatility around their trends. The difficulty in explaining this volatility has led economists to interpret it as exogenous, i.e., as the result of forces that lie outside the scope of the assumed economic relations. Consequently, it becomes hard or impossible to formulate short-run forecasts on asset prices or on values of macroeconomic variables. However, many random looking economic and financial series may, in fact, be subject to deterministic irregular behavior, which can be measured and modelled. We address the notion of endogenous volatility and exemplify the concept with a simple business-cycles model.

Embora Portugal seja um país onde tradicionalmente se mantinham elevados níveis de poupança, essa tendência esbateu-se na década passada, fruto de fatores diversos e de uma realidade sócio-económica menos favorável. Todavia, na presente conjuntura económica reveste-se de particular importância a adoção de comportamentos de poupança. É, por isso, necessário compreender claramente os fatores que estão na sua origem. Neste estudo, que envolveu uma amostra de 835 portugueses, procurámos investigar a relação entre as motivações de poupança e os comportamentos de poupança dos portugueses. Os resultados indicam que as motivações de poupança estão relacionadas com a perceção da capacidade de gestão financeira, com a elaboração de um orçamento familiar e com a frequência de poupança dos agregados familiares em Portugal.

Portugal had only very few foresight exercises on the automobile sector, and the most recent one was a survey held in a project on work organisation systems in the automobile industry, its recent historical paths and the special strategies of location of companies (the WorTiS project). This involved several teams with different disciplinary backgrounds and from two Portuguese universities. The provisional main results of the first round of a Delphi survey held in Portugal on the automotive sector were already published, but a further analysis was not yet done. This foresight survey was done under the WorTiS project, developed in 2004 by IET – Research Centre on Enterprise and Work Innovation (at FCT-UNL), and financed by the Portuguese Ministry of Science and Technology. Some of this experience on foresight analysis is also been transferred to other projects, namely the WORKS project on work organisation restructuring in the knowledge society that received the support from EC and still is running. The majority of experts considered having an average of less knowledge in almost all the scenario topics presented. This means that information on the automotive industry is not spread enough among academics or experts in related fields (regional scientists, innovation economists, engineers, sociologists). Some have a good knowledge but in very specialised fields. Others have expertise on foresight, or macroeconomics, or management sciences, but feel insecure on issues related with futures of automobile sector. Nevertheless, we considered specially the topics where the experts considered themselves to have some knowledge. There were no “irrelevant” topics considered as such by the expert panel. There are also no topics that are not considered a need for co-operation. The lack of technological infrastructures was not considered as a hindered factor for the accomplishment of any scenario. The experts’ panel considered no other international competence besides US, Japan or Germany in these topics. Special focus will be made in this paper on the topic 2. Public policy and automobile industries, and more specifically on the technological and/or research policies issues, where one can specify the automobile’s role in transport policies with further implications like environment, safety, energy, mobility.

The current economic crisis has rushed even more the economists’ concerns to identify new directions for the sustainable development of the society. In this context, the human capital is crystallised as the key variable of the creative economy and of the knowledge-based society. As such, we have directed the research underlying this paper to identifying the most eloquent indicators of human capital to meet the demands of the knowledge-based society and sustainable development as well as towards achieving a comprehensive analysis of the human capital in the EU countries, respectively of a comparative analysis: Romania - Portugal. To carry out this paper, the methodology used is based on the interdisciplinary triangulation involving approaches from the perspective of human resource management, economy and economic statistics. The research techniques used consist of the content analysis and investigation of secondary data of international organisations accredited in the field of this research, such as: the United Nation Development Programme - Human Development Reports, World Bank - World Development Reports, International Labour Organisation, Eurostat, European Commission’s Eurobarometer surveys and reports on human capital. The research results emphasise both similarities and differences between the two countries under the comparative analysis and the main directions in which one has to invest for the development of human capital.

Os ativos intangíveis são cada vez mais uma preocupação das organizações, e atualmente são reconhecidos como os principais ativos das empresas. O Capital Humano como dimensão do Capital Intelectual é um fator preponderante no desenvolvimento e crescimento das organizações, uma vez que proporciona criação de valor e vantagem competitiva para as empresas. A criação, a partilha e a transferência de Conhecimento são, também, fatores influentes que geram Capital Humano. Na atualidade, este tema tem despertado o interesse tanto de economistas, gestores e contabilistas, como de meros investidores. O Capital Intelectual é tradicionalmente concetualizado como sendo composto por três grandes dimensões: Capital Humano, Capital Relacional e Capital Estrutural. Por sua vez, daquilo que é o nosso conhecimento, consideramos que existe uma lacuna na literatura sobre Capital Humano no que diz respeito à sua taxonomia. Efetivamente grande parte das investigações sobre Capital Humano, como dimensão do Capital Intelectual, focam-se essencialmente nos itens necessários para a sua mensuração do CH. Desta forma, o objetivo principal deste estudo consiste em explorar a dimensão do CH ao nível das suas componentes. Ou seja, procuramos encontrar as componentes do Capital Humano e propomo-nos a determinar quais as que têm maior importância no CH para o desenvolvimento e crescimento das organizações. Para esta realização efetuámos um estudo de carácter exploratório, num contexto específico do mercado português – o Setor Segurador. Os resultados obtidos tanto a nível qualitativo como quantitativo vão de encontro às questões de investigação previamente definidas. Portanto, as componentes mais importantes do CH são: a formação e o bem-estar, o conhecimento e o profissionalismo e as características pessoais e técnicas dos colaboradores que constituem os Recursos Humanos da organização. Estas são aquelas que mais valorizam e proporcionam crescimento nas organizações. Este estudo poderia ser tão mais completo, se pudéssemos apresentar uma comparação entre duas empresas seguradoras e, consequentemente analisar o comportamento das duas face ao Capital Humano. Outro aspeto interessante seria efetuar uma análise sobre qual o impacto do Capital Humano na performance financeira das organizações seguradoras. Estas são limitações que podem ser vistas como sugestões para estudos de investigação futuros nesta mesma área. Este estudo contribui para o enriquecimento das investigações na área do Capital Humano, uma vez que conhecendo melhor as componentes que constituem o CH mais facilmente as organizações definem as suas estratégicas de crescimento e desenvolvimento. Desta forma, este estudo pode apoiar alguns gestores na definição de políticas de valorização deste ativo intangível em organizações do mercado segurador.

The alignment of collective goals and individual behavior has been extensively studied by economists under a principal-agent framework. Two main solutions have been presented: explicit incentive contracts and monitoring. These solutions correspond to changes in the objective situation faced by individuals. However, an extensive literature in social psychology provides evidence that behavior is influenced, not only by situational constraints, but also by attitudes. Therefore, an important aspect of organization is to choose the structures and procedures that best contribute to the dissemination of the desired attitudes throughout the organization. This paper studies how the initial configuration of attitudes and the size of the organization affect the optimal organizational structure and the timing of information flows when the objective is to align the members' attitudes. We identify and characterize three factors that affect the optimal organizational structures and procedures and the degree of alignment of attitudes: (1) clustering effects; (2) member cross-influence effects; and (3) leader cross-influence effects.
